摘　　要：文中对MIMO系统中各种基于MMSE准则的接收算法,包括线性MMSE算法、MMSE-BLAST以及MMSE-SQRD算法,对检测后系统容量带来的影响做了详细的分析与推导,给出了其具体表达式,并用计算机仿真给予验证,得出了MMSE-SQRD算法的检测后系统容量最好的结论。In this paper, three algorithms based on MMSE law in the MIMO system are presented, including the line MMSE algorithm, MMSE-BLAST algorithm andMMSE-SQRD algorithm. The impact of these three algorithms on the system capacity after detection is analyzed. And it proposes the expression of the system capacity after detection under the line MMSE algorithm and MMSE-SQRD algorithm. The theoretical analysis and simulation indicate that the system capacity of MMSE-SQRD algorithm after detection is better than the others.
